原有的 ExtensionFactory ：ExtensionLoader.getExtensionLoader(ExtensionFactory.class).getAdaptiveExtension(); 方法已经废弃，请问新的方法是哪个呢？是否能给出示例？

> Dubbo 3.0 Filter 中 获取Spring Bean 的问题
这个问题没有详细的描述，具体是什么问题？
1、在Dubbo中获取Spring context
```java
ApplicationContext applicationContext = SpringExtensionInjector.get(applicationModel).getContext();
applicationContext.getBean(BarService.class);
```
2、在SPI中通过setter方法注入Spring bean
```
public class MyFooSPI implements FooSPI {
private BarService barService;
public void setBarService(BarService barService) {
this.barService=barService;
}
}
```

3.0.3 Dubbo支持多应用实例后，ExtensionLoader也相应的支持多实例，改成通过SPI对应ScopeModel( ApplicationModel/ModuleModel/FrameworkModel) 获取ExtensionLoader。
如Application层的一个SPI：
```java
@SPI(scope = ExtensionScope.APPLICATION)
public interface FooSPI {
...
}
```
1、加载SPI实例：
```java
ApplicationModel applicataionModel = ...;
applicataionModel.getExtensionLoader(FooSPI.class).getAdaptiveExtension();
```
2、一般是通过上下文获取到ScopeModel，如：
1) URL.getScopeModel()
2) SPI 的构造函数注入
```java
public class MyFooSPI implements FooSPI {
public MyFooSPI ( ApplicationModel applicataionModel ) {
...
}
}
```
3) DubboBootstrap
4) Spring ApplicationContext
```
DubboBeanUtils.getApplicationModel(applicationContext);
DubboBeanUtils.getModuleModel(applicationContext);
```
